Answer:
x=3 y=4
Step-by-step explanation:
The diagonals in a parallelogram bisect each other
DG = GC and KG = GU
4x-7 = x+2
Subtract x from each side
4x-x-7 = x+2-x
3x-7 = 2
Add 7 to each side
3x-7+7 =2+7
3x=9
Divide by 3
3x/3=9/3
x=3
KG = GU
5y-8 = 3y
Subtract 5y from each side
5y-8-5y = 3y-5y
-8 = -2y
Divide by -2
-8/-2 = -2y/-2
4 =y
It should equal to 180 so 180-157=23
Answer:
4.46cm
Step-by-step explanation:
Volume of a frustum is expressed as;
V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))
h is the height of the frustum
r₁ and r₂ are the radii of its ends
V is the volume
Given
V = 9100cm₃
r₁ = 10cm
r₂ = 30cm
Substitute
9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))
9100 = 1/2(3.14)*h*(100+900+300)
9100 = 1.57*h*(1300)
9100 = 2,041h
h = 9100/2,041
h = 4.46cm
Hence the height of the cap is 4.46cm
